1. Equipment setting problem: Make sure that the equipment is correctly set for track swimming. Confirm whether the swimming tracking option is enabled by checking the device settings and applications.
2. Device compatibility: Some Huawei devices do not support the display of swimming trajectories. Check the device model and operating system version to confirm whether this function is supported.
3. Incorrect operation: Before swimming, make sure that the swimming tracking function is activated correctly.
4. Environmental problems: When swimming indoors, the signal will be shielded when the equipment is underwater, which makes it impossible to accurately track the track.
If the above methods can't solve the problem, I suggest you contact Huawei customer service or uninstall and reinstall Huawei Health Application. If the problem still exists, it is recommended that you go to Huawei authorized maintenance service center for overhaul and maintenance.
